Abstract

The present invention discloses a method of correcting a video signal that includes a video sequence parameter. The method comprises the steps of: obtaining a specific number of decoded values of the video sequence parameter; counting the times of occurrence of each different value of the decoded values; determining a correction value from the counting result; and correcting the decoded values of the video sequence parameter on the basis of the correction value. The present invention further discloses a correcting apparatus and a decoding apparatus of a video signal. With the present invention, it is able to find out conveniently a correction value of a video sequence parameter so as to correct the subsequent decoded values.
